example of freeze, always at the same time

[Cinikus]

Here is some example of freeze, problem happen at the same time every time unless i change my main character.
I'm not against buying options for a game i like but there is too many freeze in this game to do it.

Ipad air 2, latest release of IOS

First picture is the lvl, 2nd picture after the freeze.

that's just 2 example, there is much more in the 3rd world, Fortress lvl.
